我正在尝试MongoDB从从MongoDB站点下载的Zip文件夹安装（https://www.mongodb.com/download-center/enterprise/releases/development）

我正确配置了日志路径，数据路径，并尝试启动mongod并获取以下依赖项错误。

amran:~$ mongod
mongod: /usr/lib/x86_64-linux-gnu/libcurl.so.4: version `CURL_OPENSSL_3' not found (required by mongod)

libcurl.so.4 存在于我的机器中

amran:~$ locate libcurl.so.4
/usr/lib/x86_64-linux-gnu/libcurl.so.4
/usr/lib/x86_64-linux-gnu/libcurl.so.4.5.0

如何解决此问题。任何想法请！

我收到以下错误:

程序无法获取集合属性.

        MongoClient mongoClient = new MongoClient(new ServerAddress("localhost", 27017));

        MongoDatabase db = mongoClient.getDatabase("local");

        MongoCollection collection = db.getCollection("sadi");

        BasicDBObject searchQuery = new BasicDBObject();
        searchQuery.put("name","amran");
        DBCursor cursor = collection.find(searchQuery);

我想在actionItem()函数里面显示Toast.但它现在没有显示Toast.

如果我打电话

Context context = getApplicationContext();

在actionItem()之前,应用程序崩溃了.

import android.content.Context;
import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.Toast;


public class ShowWebViewActivity extends ActionBarActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.show_web_view);

    }


    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_show_web_view, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle …

如何从这段代码中计算满足lower_bound(42),upper_bound(137)的元素数？

accumulate(values.lower_bound(42), values.upper_bound(137), 0);

我想使用两个变量的cp命令,但不起作用

#!/bin/sh

PATH="/home/smvm/Dropbox/ssd-tech/SoftSwitch"


SRCPATH=${PATH}/lib/SIPLib/*.a
DESTPATH=${PATH}/include

cp "$SRCPATH" "$DESTPATH"

发生以下错误

copyPaste.sh: 9: copyPaste.sh: cp: not found
